Colonial Furniture Co. uses a standard cost system. One of the company’s most popular products is a cherrywood desk. The per-unit standard costs of the desk, assuming a “normal” volume of 2,000

 

J  urnalizing, and

 

units per month, are as follows:

Instructions

a.       Compute the following cost variances for the month of May:

1.      Materials price variance

2.      Materials quantity variance

3.      Labor rate variance

 

 

 

 

4.      Labor efficiency variance

5.      Overhead spending variance

6.      Volume variance

b.       Prepare journal entries to assign manufacturing costs to the Work in Process Inventory account and to record cost variances for May. Use separate entries for (1) direct materials, (2) direct labor, and (3) overhead costs.

c.       Comment on any significant problems or areas of cost savings revealed by your computa- tion of cost variances. Also comment on any possible causal relationships between significant favorable and unfavorable cost variances.
